To all whom it may concern .7

Be it known that I, AI C. GORDON, citizen of the United States, residingat Glens Falls. in the county of Warren and State of New York haveinvented certain new and useful :hroken away,x showing one of thesections tdietac'hed.

I r In order that the construction,mounting Improvements in AuxiliarySteam Generators, of. which the following is a specification.

This invention relates to an improved auxiliary steam generator for shippower systems and has asritsprimary object to pro vide a device of thischaracter adapted to utilize the waste heat from. the ships boilers forgenerating steam which may be used along with the steamfroin the boilersfor propelling the ship or for any other purpose desired- I Theinvention has as a further object .to provide device of the abovedescribed character adapted to be interposed in one oi the smoke-fines.of the ships boilers and providedwith awater jacket so that the heatpassing through the hue and through the device will be utilized forheating the water within the said jacket to generate stcam therefrom.

The invention has as a still further object to provide a device of theabove described character: which. will be formed in sections or units sothat'- the size of thedevice may be varied to suit the conditions ofdifferent ships by simply increasingor decreasing the number ofsectlon's or unitsemployed.

And the invention has as a stillfurther object to provide an improvedarrangement embodiment of the invention and wherein .slmilar referencecharacters deslgnatecorresponding parts throughout the several viewsFigure 1 1s a fragmentary elevation showingmy improved devicein.connection with j erator, like the terminal sections, each ina;conventional type-of shipis boiler; three of the decks of the ship beingalso conventionally shown in section.

Fig.4: is adetail perspective view, partly and operation of my improvedgenerator rnay be accurately understood, I have, in :the drawings; shownthedevice in connection with a conventional. type of ships boiler 10having a smoke flue l1 and steam dome 12 Thedirst, second. and thirddecks of the ship are also conventionally shown at 13. Coming now moreparticalarly to the subject of the present invention, my improved deviceis formed with a body made up of a plurality of cylindrical sections orunits: and Including terminal. sect ons'li and 15 re .sp'ectively,between which are arranged a plurahty of Intermechate sections 16 Theterminal sections 14 and 15 each include a rality of parallelcirculating. pipes 21 opening into the water jacket and provided at thelower sides thereof-with flat upwardly diverging. deflecting faces fordirecting heated currents through the casing toward the wall thereof formore eflectuallyheating Formed on the water. jacket thereon is. aplurality of. radially extending tubular passages QQ-Which arevertically disposed. Preierably, these passages are of a radiuscorresponding to the width of the waterjacket. Opening into one of thepassages of the section 14 is an inlet23- and H communicating With oneof the passages of the section 15 is an outlet 24.

The intermediatesections 16 of the gencludea cylindrical casing 25surrounded by an annular water jacket 26 closed at its ends Formed onthe Water jacket at quadrantly spaced points are a plurality of verticaltubular passages 29 corresponding to the passages 22- of the terminalsections. It will thus be clear that the terminal and intermediatesections are. as shown in Fig. 2 of the drawings, adapte to mate end toend for forming the generator when the passages 22 and 29 of thesections will aline vertically of the generatorbody to providepassageways extending from end to end thereof. However, in thisconnection it hould be noted that the said sections are so arranged oneupon the other that the circulating pipes of one section are disposed atright angles to the pipes of the preceding section. Formed at the innerends of the passages 22 of the terminal sections 14 and 15 areoppositely directed lateral ear or lugs 30 and fitted through these lugsto extend at opposite sides of each of the passageways are'tie rods 31detachably connectingthe said sections. The sections are thus rigidlyheld together to provide a continuous smoke passage through the bodyand, as shown in Fig. 1, the body is inter.- posed in the smoke flue 11of the boiler 10 to extend vertically above the boiler with the reducedextension 19 of the section 14 of the generator body receiving one endof the flue while the opposite end of the flue is fitted over thereduced extension 19 of the section 15. Thus, the waste products ofcombustion from the boiler will flow through the generator. In Fig. 1-,I have shown the generator of a length to extend upwardly through thefirst and second decks of the ship. However, as will be clear in view ofthe preceding description, the length of the generator may be readilyvaried to suit the conditions of different ships or the requirements ofdifferent boilers by simply increasing or decreasing the number ofsectlons employed in the body of the generator.

: As will now be observed upon reference to 'Fig. 2, the end walls 20and 27 of the sections are, at the passages 22 and29, formed withreglstering openings and detachably engaged within these openings aredouble ended coupling nipples 32 wedged at their ends within the saidopenings and establishing communication between the passages,

'mak-ing f the passageways continuous, vertically of the generator body.This construction provides a very convenient arrangement whereby thepassages of the sections may be readily connected and since the nipplesare arranged to establish communication directly between the ends of thepassages, the said passages will, by being enlarged radially withrespect to the water jackets, provide free circulation between the waterjackets of the sections. Connected with the inlet 23 of the section 14is a pipe 33 communicating with which is a water supply pipe 34: havinga usual cut off valve 35 interposed therein. The pipe 33 is earried to awater tank 36 mounted on a level adjacent the upper extremity of thegenerator. Accordingly, this tank is, as shown in Fig. 1, arranged uponthe second deck of the ship and is preferably equipped with a sight tube37 Controlling communication between the tank and the pipe 33 is a usualshut off valve 38 in the said pipe. Leading from the outlet 24: of thesection 15 is a steam line pipe 39 which is connected with the steamdome 12 and leading from the said dome in communication with the pipe 39is a steam supply pipe 4:0 in which is preferably interposed a usual outoff valve 11." Leading from the pipe 39' to the tank 36 is a branch pipe42 and preferably a usual cut off valve 43 is interposed in the pipe 39between the generator and this branch pipe.

In use, water is admitted through the pipe 34 to flow into the generatorand into the tank 36, the level of the water in the generator beingeasily determined by means of the sight tube 37 upon the tank. In orderto allow for the rolling of the ship, the tank is preferably onlypartially filled with a corresponding-partlal filling of the generator,so that space may be allowed in'the uppermost sections of the generatorfor rise and fall of the water therein with the movement of the ship. Aswill, of course, be understood, the water will, when the generator 15thus filled,'flow into the circulating pipes 21 and 28 so that the wasteproducts of combustion of the boiler 10 is passing through thegeneratoras previously described, will flow over these pipes and againstthe walls of the flue passage of the generator for heating the watertherein. The steam thus generated will then be carried off through theently of such boiler supply for driving other.

machinery upon the ship.

Having thus described the invention, what is claimed as new is:

1. An auxiliary steam generator including a body having a casingproviding a continuous centralsmoke passage openingthrough the ends ofthe body, a water jacket surrounding the casing and uniformly spacedtherefrom, the body being formed of inde-' pendent detachably connectedsections and the space between the jacket wall and the wall of thecasing upon each of the sections lll being uninterrupted, a waterpassageway formed on the walls of the jackets and open to the jackets,said passageway being enlarged to project outwardly from the jacketwalls and establishing communication between the jackets of thesections, and an inlet and outlet for said jackets.

2. In a device of the character described, the combination with a boilerincluding a flue, of an auxiliary steam generator interposed betweenlengths of the fiue to form a continuation thereof and having a Wateracket, a water supply tank, circulating pipes leading from the jacket atopposite ends of the generator and connected with opposite ends of thetank, a pipe forming an extension of one of said first mentioned pipesand having direct connection with the boiler for carrying off steam fromthe jacket, and valves interposed in said circulating pipes whereby saidvalves may be closed to cut off communication between the tank andjacket and the generator displaced from the flue.

In testimony whereof, I affix my signature.
